\caption*{\footnotesize \textit{Notes:}          The table presents the ex-post Minimum Detectable Effect (MDE) sizes for         the marginal effect of cash incentives, assuming 80 percent          power and the 5 percent significance level.          The marginal effect of cash incentives is the effect of HEEC minus the effect of HEE (i.e., $\beta_2 - \beta_1$ in Equation \ref{reg-equation}).         The MDEs are obtained as 2.8 times the          standard error (SE) of the estimate, and then expressed as a proportion          of the control group standard deviation (SD).          Panels A and B correspond to          Tables \ref{table-midline-knowledge-aggregate} and \ref{table-endline-knowledge-aggregate}, respectively.         For example, in Panel A, Column 1, the value 0.012 is the SE of          $\beta_2 - \beta_1$ in Table \ref{table-midline-knowledge-aggregate}, Column 1.}
